No Fuel Gauge Reading

I have a 1998 Country Coach. The needle on my fuel gauge is pegged all the way to the right past the full mark. The gauge is made by Datcon. I'm going to check the ground connection. How can I tell if its the gauge or the sending unit. I can say that the needle will bounce just a little when I am down to what I calculate to be 1/4 tank. I use my trip meter to figure out how much fuel I have. I have a 110 Gallon tank. When I travel about 800 miles then I know I have about 20 gallons left in the tank. Before I pull away from the fuel pump I reset the trip meter. Any advice would be greatly appreciated. We are getting ready for at trip from Cape Cod to Lancaster Ca. in a few weeks

    If memory serves me correctly. There is a removable cover on the top of you instrument panel, that will allow you to get to the fuel gauge wires. Remove the wire that comes from the sending unit and the gauge should drop to empty. If it drops to empty, then you either need a new sending unit or the wire from the sending unit is grounded. If the gauge don't drop to empty, the gauge is faulty. On some CC the sending unit can be accessed by reaching over the top of the propane tank.

    Not sure what the access to your fuel tank would be, but if you can get to the connection on the tank where the sending unit for the gauge is, unplug it and the gauge should go to empty when the ignition is on...if it does, the in-tank sender is probably bad...if it doesn't, the wire to the gauge is probably grounded somewhere...doubtful that the gauge is bad since it does read something...sorry I can't help any better than that.
